Surveys, Section 3.

1. Special Survey Requirements

1.1 Special Requirements for Patrol Boats

1.1.1 Steel Crafts

TL Rules, Classification and Surveys, Section 3, A to K are to be applied for steel crafts.

1.1.2 Aluminium Alloy Crafts

In addition to TL Rules, Classification and Surveys, Section 3, A to K, following requirements are to be applied for

aluminium alloy crafts:

1.1.2.1 Surveys in general

For all periodical surveys, the requirements of Section 3 are to be fulfilled. However, in the case of crafts more than 15

years old, the frequency of the bottom survey is subject to special consideration.

1.1.3 Fiber Reinforced Plastic (FRP) Crafts

In addition to TL Rules, Classification and Surveys, Section 3, A to K, following requirements are to be applied for FRP

crafts:

1.1.3.1 Surveys in general

For all periodical surveys, the requirements of Section 3 are to be fulfilled. However, in the case of crafts more than 15

years old, the frequency of the bottom survey is subject to special consideration.

1.1.3.2 Surveys During Construction

1.1.3.2.1 With reference to lamination, special inspections are required at the following stages.

For hand lay-up lamination:

a) when the hull lamination starts with the application of gel-coat;

b) during the hull lamination at different stages;

c) before starting the arrangement of internal stiffeners;

4


d) when the hull is extracted from the mould;

e) when the connection of the hull to the deck starts;

f) before the installation of the dolly, if any;

g) when the core of sandwich structure is arranged.

1.1.3.2.2 For particular lamination processes in enclosed mould, such as infusion lamination, the lamination survey

scope is to be agreed with the TL Surveyor, but in any case special inspections are required at the following stages:

a) at the application of the release agent and the gel coat prior to starting with application of the laminate;

b) when the dry reinforcements layers and cores are fitted on the mould;

c) at the vacuum application for the initial check prior to starting with the lamination and related to:

• consolidation of the bag

• vacuum application

• vacuum/leakage control

d) during the resin infusion to verify and record the following data:

• waiting time

• infusion time

• vacuum level during the infusion

e) after the bag take-off to inspect the result of the lamination

f) before starting the arrangement of internal stiffeners

g) when the hull is extracted from the mould for the final inspection;

h) when the connection of the hull to the deck starts;

i) before the installation of the dolly, if any.

1.1.3.2.3 When thermosetting resins are employed, attention is to be payed to the type and quantity of catalyst agent

employed so as to be compatible with the resin and the temperature and humidity of the space where composite

fabrication and the curing process take place.

1.1.3.2.4 On the basis of the internal controls of the shipyard, the TL Surveyor may not attend some of the above

inspections, provided that satisfactory records and internal checks are be submitted.

1.1.3.2.5 In addition, during the supervision of the first hull, an inspection of the shipyard is performed in order to verify

that it is provided with adequate equipment in relation to the materials used and to the type of manufacture and that the

quality of the laminates is ensured.

1.1.3.3 Periodical hull surveys

1.1.3.3.1 Annual and intermediate surveys

In the case of hulls made of sandwich type structures, it is to be carefully checked that the parts are not detached from

the core. The check is to be performed by hammering the shell and evaluating the differences in the sound heard or by

means of checks with non-destructive methods recognised by TL.

The connection between hull and deck is to be carefully checked, in particular when hull and deck are made of different

materials.

1.1.3.3.2 Class renewal survey (hull) and bottom survey in dry condition

In addition to the requirements for the intermediate surveys given in 15.2.1.3.3.1, the presence of "osmosis" phenomena

in the laminates of the underwater body and/or of cracks in the gel-coat is to be verified.

To this end, the craft is to be made available for the bottom survey in dry condition before the application of any paint, so

as to allow a careful visual inspection.

In-water survey in lieu of bottom survey in dry condition will be specially considered by TL on a case-by-case analysis.

1.1.3.4 Examination and testing – Additional items for composite craft

The bonded attachments of frames, floors, bulkheads, structural joinery, engine bearers, sterntubes, rudder tubes, and

integral tank boundaries are to be examined.

The hull to deck joint together with any joints between the deck and deckhouses or superstructures are to be examined.

The structure in way of the bolted attachment of fittings including guardrail stanchions, windlass, shaft brackets,

fendering, mooring bitts, mast steps, rigging chainplates, etc., is to be examined.

External hull structure are to be specially examined:

For composite hulls the gelcoat or other protective finish is to be examined for surface cracking, blistering or other

damage which may impair the efficiency of the protection to the underlying laminate.

1.1.3.5 Suspect areas

Suspect areas are locations within the hull structure vulnerable to increased likelihood of structural deterioration and may

include:

6


For composite hulls, areas subject to impact damage.

1.1.3.6 Ballast Keel

In composite crafts care is to be taken to prevent crushing of GRP laminates through overtightening of keel bolts.

In the case of composite structures, including steel and GRP, consideration will be given to the use of steel rivets.

4.2.1 General For crafts which are less than 24 m.; 4.2.1.1 Machinery spaces of major fire hazard, galleys above 10 m

2 and storage spaces for ammunition shall

be enclosed by steel or equivalent fire resisting divisions. For ammunition stores, the insulation shall be provided on the external boundaries of the space, except where bounding tanks, voids and open spaces. 4.2.1.2 Principal partition is to have an A-30 insulation. For steel structures, A-0 towards void and open spaces is considered sufficient. Note: A principal partition is the partition (bulkhead or deck) between machinery space on one hand and the steering position or cabin above or adjoining on the other. 4.2.1.3 No structural fire protection requirements are applicable to areas other than specified in first paragraph. 4.2.1.4 In spaces where the penetration of oil products is possible, the surface of insulation shall be impervious to oil or oil vapors. 4.2.1.5 Paints, varnishes and other finishes used on exposed interior surfaces are to be of an approved low flame-spread type and shall not be capable of producing excessive quantities of smoke and toxic products. 4.2.1.6 No requirements related to restricted use of combustible materials and smoke-tight division will apply.

4.2.2 Escape ways and arrangement 4.2.2.1 All spaces shall be provided with satisfactory means of escape through corridors, stairways or other spaces independent of the space considered, all with a minimum free opening of 700 mm in all directions. Where a secondary means of escape is required, this can be provided by a permanent ladder and hatch arrangement with a free opening of minimum 500 mm in all directions. Doors and hatches not capable of being unlocked from both sides shall not be regarded as an escape way. 4.2.2.2 Escape routes shall be separated from adjacent spaces by at least class B divisions. 4.2.2.3 Dead-end situations exceeding 7 m in length shall be avoided in any case. 4.2.2.4 For accommodation spaces, two means of escape from every restricted space or group of spaces shall be provided unless there is a means of escape that leads directly to the open deck. 4.2.2.5 For machinery spaces of major fire hazard, two means of escape shall be provided, except where the space has a length of less than 5 m and direct access to open deck is provided. 4.2.2.6 Below the lowest open deck at least one means of escape shall be independent of watertight doors. 4.2.2.7 Fire doors need not be remotely operated or self closing. However, where fire doors bounding areas of major fire hazard are not self closing, they shall be normally shut and fitted with indicators to provide warning in the control station when the doors are not completely closed. 4.2.2.8 Fuel oil tanks may be located contiguous to machinery spaces of major fire hazard provided the boundary between such spaces and fuel oil tanks are protected with 60 minutes fire-resisting divisions. 4.2.2.9 Petrol for auxiliary purposes may be stored in limited volume. Petrol shall only be stored on open deck or in compartments effectively ventilated to open deck. The storage position shall be so arranged that under no circumstances can inflammable or explosive fluids or gases accumulate, for example, in lower parts of the hull.

4.2.3 Fire Detection

4.2.3.1 Fire detection systems 4.2.3.1.1 An approved automatic fire detection and alarm system shall be installed, to indicate, at the craft's control station, the location of an outbreak of fire. In the event that the control station is unmanned, an audible alarm shall be automatically sounded throughout the crew compartments. 4.2.3.1.2 All enclosed spaces, except areas of no fire risk and limited areas of minor fire risk such as void spaces and bathrooms of limited area within cabins, shall be provided with fire detectors. Spaces with floor area below 4 m

2 and ceiling area below 6 m

2 shall in this context be considered spaces of limited area.

4.2.3.1.3 Patrol boats need not be fitted with TV cameras in main propulsion machinery room.
